This isn't quite true, where addiction / compulsive usage can be implicated. Still, it's true that FB isn't completely in the pocket of advertisers and such. To the extent that they do make transgressions against their users, they will tend to not be overt.

FB doesn't have to make its users happy (whatever that means) so much as not piss them off.
